Landlord and commercial work in Mansewood
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
External mastic in Mansewood
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. If you’re dealing with weathered mastic that no longer stretches and damp patches traced to an open external joint, we can put it right, whatever the surface.
Gutters and downpipes on tall city tenements are a long way up, so a leaking joint can run down the stone for months before anyone notices. In Mansewood, access needs planning, and work on shared parts may need the other owners’ agreement.
The work is covered for a year after we finish. If anything isn’t right with it, drop us a line at info@mrmastic.co.uk.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What we are called out for in Mansewood
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
Most people get in touch after spotting something like this:
- Old sealant gone brittle and cracked
- Failed sealant between panels on a façade
- Sealant pulling away from one side of the joint
- Gaps where render, brick and frames meet
Letting a property close to Pollokshaws West station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Advice
What external mastic looks like in Mansewood
Mansewood is in the west of Scotland, which is wetter than the east, which means movement joints and outside wall joints has to cope with a lot of rain. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Hillpark Secondary School, its movement joints, gutters and trims need looking after like any other building’s. For an older house near a landmark such as Pollokshaws Parish Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Common questions in Mansewood
Do you work for landlords with property near Pollokshaws West station?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
How is work on the outside of a tenement in Mansewood generally arranged?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Your title deeds will say who owns the windows.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
What is a movement joint?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking and needs a flexible seal, not mortar.
How do I get a quote for external mastic in Mansewood?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Is it OK to fill a movement joint with cement?
No. A mortar-filled joint cannot move, so the wall cracks somewhere else instead. Use a flexible sealant with backing rod.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

When it isn’t the sealant
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Render that’s blown, hollow or coming away
- Movement that’s more than a sealant joint can take
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
